Definitions

• compositions are those wherein the mixture of essential components, namely the hair styling polymer, silicone microemulsion, and carrier is a substantially homogeneous solution or dispersion (preferably microdispersion), more preferably substantially clear to translucent in appearance.
• Preferred final compositions are those also characterized by these properties.
• Preferred cationic polymers are Polyquaternium-4; Polyquaternium-10; Polyquaternium-11 ; Polyquaternium-16; PVP/Dimethylaminoethylmethacrylate; Vinyl Caprolactam/PVP/Dimethylaminoethyl Methacrylate copolymer; and Chitosan.
• the emulsion can be prepared by the emulsion polymerization process described in EP 459500 (published December 4, 1992), incorporated herein by reference.
• stable, oil free polysiloxane emulsions and microemulsions are prepared by mixing a cyclic siloxane, a nonionic surfactant, an ionic surfactant, water, and a condensation polymerization catalyst.
• the mixture is heated and agitated at polymerization reaction temperature until essentially all of the cyclic siloxane is reacted, and a stable, oil free emulsion or microemulsion is formed.
• the reaction mix, especially surfactant levels, and conditions are controlled in order to provide the desired organopolysiloxane particle size.
• Ionic surfactants useful in preparing the microemulsion include any conventional anionic surfactant such as sulfonic acids and their salt derivatives. Ionic surfactants also include any conventional cationic surfactant used in emulsion polymerization. Surfactants of these types are well known in the art and are commercially available from a number of sources. Specific examples of these surfactant types are also disclosed in the above referenced patent application Serial No. 08/929,721.
• compositions of the present invention comprise one or more suitable solvents for the hair styling polymer.
• suitable solvents for the hair styling polymer are those which form a homogeneous solution or dispersion (preferably microdispersion) with the hair styling polymer in the weight ratios used in the composition.
• Prefened solvent systems are those which form a substantially clear to translucent solution or dispersion (preferably microdispersion) with the hair styling polymers in the weight ratios used in the composition.
• Amphoteric surfactants include those which can be broadly described as derivatives of aliphatic secondary and tertiary amines in which the aliphatic radical can be straight chain or branched and wherein one of the aliphatic substituents contains from about 8 to about 18 carbon atoms and one contains an anionic water solubilizing group, e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate.
• anionic water solubilizing group e.g., carboxy, sulfonate, sulfate, phosphate, or phosphonate.
• Examples of compounds falling within this definition are sodium 3- dodecylaminopropionate, N-alkyltaurines such as the one prepared by reacting dodecylamine with sodium isethionate according to the teaching of U.S.
• Nonionic surfactants include polyethylene oxide condensates of alkyl phenols (preferably C6-C12 alkyl, with a degree of ethoxylation of about 1 to about 6), condensation products of ethylene oxide with the reaction product of propylene oxide and ethylene diamine, condensation products of aliphatic alcohols with ethylene oxide, long chain (i.e., typically C12-C22) tertiary amine oxides, long chain tertiary phosphine oxides, dialkyl sulfoxides containing one long chain alkyl or hydroxy alkyl radical and one short chain (preferably C1 -C3) radical, silicone copolyols, and C1-C4 alkanol amides of acids having a Cg ⁇ C22 ac yl moiety.

• Neutralization can be accomplished by techniques well known in the art, and before or after polymerization of the monomers comprising the hair styling polymer. d) Hair Conditioning Polymers
• Cationic and zwitterionic hair conditioning polymers are prefened.
• Suitable hair conditioning polymers include cationic polymers having a weight average molecular weight of from about 5,000 to about 10 million, and will generally have cationic nitrogen-containing moieties such as quaternary ammonium or cationic amino moieties, and mixtures thereof.
• Cationic charge density should be at least about 0.1 meq/gram, preferably less than about 3.0 meq/gram, which can be determined according to the well known Kjeldahl Method. Those skilled in the art will recognize that the charge density of amino-containing polymers can vary depending upon pH and the isoelectric point of the amino groups. The charge density should be within the above limits at the pH of intended use. Any anionic counterions can be utilized for the cationic polymers so long as they are compatible.
• the silicone polyether is used in an amount effective to stabilize the microemulsion, preferably from about 0.02% to about 7%, more preferably about 0.05% to about 5%, of the total composition.
• the silicone polyether may be a silicone - linear polyoxyalkylene block copolymer (wherein the polymeric backbone comprises silicone blocks and polyoxyalkylene blocks, optionally having grafts), a silicone - graft polyoxyalkylene copolymer (wherein the polymeric backbone comprises silicone blocks and the polyoxyalkylene blocks are present as grafts rather than in the backbone), or a mixture thereof. Linear copolymers are prefened.
